Thermography
Thermal imaging surveys that spot overheating electrical connections, motors and mechanical faults before they cause a fire or unplanned downtime.
How it works
Heat is one of the clearest warning signs in any electrical or mechanical system — and one of the easiest to miss until it's too late. A loose lug, an overloaded circuit or a failing bearing all generate excess heat long before they trip a breaker or seize completely.
Our thermographers survey electrical panels, motor control centres (MCCs), switchgear and mechanical drive components with calibrated thermal imaging equipment, flagging any component running hotter than its neighbours or its design tolerance — non-contact, without interrupting operations.
What our thermography covers
- Electrical panel inspections — hot joints, overloads, phase imbalance
- Motor and bearing overheating detection
- Belt slippage and friction identification
- Insulation and refractory condition assessment
- Steam trap and process blockage detection
- Insurance and compliance reporting support
Signs it's time for thermography
Ageing electrical infrastructure that has never been thermally surveyed
Recent load changes, retrofits or panel modifications
Insurance or compliance requirements for periodic thermal audits
A history of nuisance trips or unexplained downtime
Common questions about thermography
Does thermography require a plant shutdown?
No. Electrical thermography is most effective under normal operating load, so surveys are done live, with strict safety protocols and appropriate PPE.
How often should electrical thermography be done?
Annually for most electrical distribution systems is standard practice in South Africa, with more frequent surveys for critical or high-load panels.
Can thermography replace an electrical compliance certificate?
No, but it's a strong complementary tool — it finds developing faults that a visual inspection alone would miss.
